How this service works
Single-connection meta-router indexing 500+ MCP servers & A2A tools with 85% token compression and Prompt-Guard firewall. (Live x402 v2, IETF MPP & MCP endpoint at https://x402broker.com/v1/b2b-osint-dag)
Output
Returns a compressed, structured listing of matching MCP servers and A2A tools relevant to the search query, including capability descriptions and endpoint metadata, filtered through a prompt-injection firewall for safe consumption by downstream agents.
Example use cases
Discover tools for OSINT workflows
“Search the meta-router for any MCP servers or A2A tools that can do domain OSINT, TLS inspection, or security header analysis — I want to see what's available before I build my recon pipeline.”
Find context compression capabilities
“I need to reduce token usage in my agent — can you search the tool index for anything related to context compression or token budget control?”
Verify and route to a specific endpoint
“Check if the endpoint at https://x402broker.com/v1/web-distill is indexed and available in the tool router, and tell me what capabilities it exposes.”
Technical details
Endpoint
GEThttps://x402broker.com/v1/b2b-osint-dag?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover which tools or MCP servers can satisfy a capability requirement at runtime, rather than hardcoding a specific API. Especially useful for multi-agent swarms that need to delegate subtasks to specialized tools without pre-configuring each integration. Prefer over direct API calls when the best tool for a job is unknown in advance or when building a tool-agnostic orchestration layer.
Side effects
- Empty or too-vague query returns no matches or overly broad results
- Endpoint URL verification fails if the target is not indexed
- Rate limiting or 402 payment required if quota exceeded
- Firewall may block or sanitize queries containing prompt-injection patterns
- Generic capability terms like 'search' may return too many results to be actionable
